Serial No. 517,603.

To all whom it may concern:

Be it known that I, JOHN B. JOHNS, a citizen of the United States, and aresident of F airmont, in the county of Marion and State of estVirginia, have invented a new and Improved Horse-Feeding Machine, ofwhich the following is a full, clear, and exact description.

Among the principal objects which the present invention has in view are:to provide a machine wherein grain may be meas ured in bulk quantity toagree with weight; to provide a machine wherefrom various quantities maybe delivered, the regulator for said quantities being operated by meansof selecting devices; to provide a simple and effective measuring devicecontrolled by a single construction to produce a variety of effects; andto provide a construction for a machine of the character specified whichis simple, durable and efficient.

One embodiment of the present invention is disclosed in the structureillustrated in the accompanying drawings, in which like characters ofreference denote corresponding parts in all the views, and in whichFigure 1 is a top plan view of a measuring apparatus constructed inaccordance with the present invention; Fig. 2 is a horizontal sectionalview taken on the line 2-2 in Fig. 8; Fig. 3 is a vertical section ofthe apparatus taken on the line 33 in Fig. 2; Fig. 1- is a cross sectionof the base of the apparatus taken on the line 4-4t in Fig. 2; Fig. 5 isa detail view of the cutofl:' plate employed in this apparatus; Fig. 6is a vertical sect-ion of the base of the apparatus taken on the line 66in Fig. 2, showing the governing delivery tube in lowered position; Fig.7 is a view similar to Fig. 6 showing the governing delivery tube inraised position; Fig. 8 is a longitudinal vertical section of themeasuring compartment of the apparatus taken 011 the line 8-8 in Fig. 1,the governing delivery tube being shown in lowered position; Fig. 5) isa view similar to Fig. 8, showing the governing delivery tube in raisedposition; Fig. 10 is a plan view of a portion of the operating devicesfor the measuring apparatus; Fig. 11 is a detail view in plan of one ofthe sliding plates of the operating devices for the measuring apparatus;Fig. 12 is a detail view in plan of one of the graduated plates of theadjustment devices for timing the operation of the operating devices forthe measuring apparatus; Fig. 13 is a detail view in side elevation ofthe rack bar for operating the measuring apparatus; Fig. lt is avertical section taken on the line l414c in Fig. 10; Fig. 15 is avertical section of the coin or token receptacle and rack bar foractuating the measuring apparatus; and Fig. 16 is a detail view in sideelevation of one of the locking devices for the coin or token mechanism.

In establishments where the usefulness of the present invention will befound of greatest advantage, the grain is purchased in large singlequantities, and as a rule, by Weight. In the same establishments thegrain is distributed by measure. The meas uring of the grain may beperformed by the superintendent or store keeper, or by the hostlersindividually. In such establishments book accounts are kept, andsupplies are included in the operation cost and figured somewhat withreference to the estimated cost of feed for a certain head of horse orcattle. It usually arises that this estimate is found to be in error.The error is usually assumed to be due to pilfering or wastage on thepart of the hostlers. I have found that the error arises from the factthat grains vary considerably in weight for a given. quantity. Assumingon the basis of weight that a quart of cats is the equivalent of apound, the bookkeeper in such an establishment as portrayed, concludesthat he has so many quarts in the ton of oats purchased. The number ofquarts required for feeding the stock per diem divided into the totalnumber of quarts gives me the number of days that the ton of oats shouldlast. If, however, as often occurs, the quart of oats weighs one and aquarter pounds, the ton of oats will last only eighty per cent. of thecalculated time. Vith careful feeders of stock it is desired to feedentirely by weight, but to weigh the supply on the usual scales causesconsiderable delay, and therefore the measuring system is in vogue, itbeing assumed that a quart measure of grain has a definite weight.

It is to obviate the various objections arising from the above describedsystem that I have provided the present apparatus. In this-apparatus thegrain is delivered by means of a supply pipe 21 from a hopper 22, or anysuitable source of supply, such as an overhead pen. A pipe 27 isprovided with strap brackets 23, 23, the upturned ends whereof engagebolts 24, 24 which are upset from a collar 25 which is secured rigidlyto the top 26 of a feed box A. The pipe 27 is slidably mounted in thelower end of the pipe 21. The lower extremity of the pipe 27 is providedwith an internal funnel mouth piece 28. The lower end of the funnelmouth piece 28 is contracted to a smaller diameter than a pipe section29 rigidly mounted upon the top 26 and extended within the feed box A.The pipe section 29 is pro vided with an annular flange 30 by which itis clamped between plates 31 and 32. The plate 31 forms, in conjunctionwith a plate 33, a slide for a cut-off plate 34, which controls theopening between the pipe 27 and the pipe section 29. The plate 34 is ofthe shape substantially as shown in Fig. 5 of the drawings, with anopening 35 through which the grain passes when said opening is alinedwith the pipes 27 and 29. Telescopically mounted upon the pipe 27, andsurrounding the same, is a pipe section 36. The pipe section 36 is ofsuflicient length to be extended to rest upon the trap door 37 of ahopper 38. The trap door 37 is normally open, as shown in Fig. 6 of thedrawings. WVhen, however, the opening 35 is moved into line with thepipes 27 and 29, the door 37 is closed, as shown. in Fig. 7 of thedrawings. hen the door 37 is thus closed the hopper 38 is in conditionto receive the grain delivered from the pipe 29.

The quantity of'grain delivered into the hopper 38 is regulated by thelift of the section 36. Grain, as do all dry comminuted material, flowsto a certain upper inclined surface formation. \Vhen delivered from acentral point this formation will be conical, the sides of the conevarying with the character and size of the material being handled. Thus,with regard to the height of the col.- umn contained in the pipes 27 and29 and the section 36, the grain will not flow from under the edge ofthe section 36 to a height greater than the flattened cone shapereferred to. Therefore, the measuring in the present invention isregulated by raising and lowering the section 36 within the hopper 38.The grain contained in the pipe 29 and section 36, when the said sectionis lowered to the door 37, is the minimum unit of weight handled by thismachine. As the section is raised the material spreads from under thebottom of the said section and increases the volume carried above thedoor 37 in proportion as the said section is thus raised. To raise thesection 36 I have provided a shaft 39 upon which are fixedly mountedquadrants 40, 40. The quadrants 40 are two in number and extend toeither side of the hopper 38. Anchored at 41, upon the said quadrants40, are lifting chains or cables 42, 42. The chains or cables 42 areextended over pulleys 43, 43 and threaded through weights 44, 44. Thearms 45, 45 form guide sockets 46, 46, and are rigidly attached at 47,47 to the section 36. The outer ends of the arms 45 are secured upon theweights 44, the sockets 46, 46 of the said arms forming guide membersfor both the said arms and the said weights. When the weights 44 areraised by the cables 42, the said arms 45, and the section 36 fixedlyconnected therewith, are likewise raised.

The shaft 39 is rotated to lift the section 36 to a series of pipes, bymeans of a series of distinct operating mechanisms which are operated bythe interposition of coins or tokens X. There is illustrated in Fig. 1of the drawings a selective mechanism whereby the section 36 may beraised to six ascertained and various heights and fractions thereof tocorrespond to the six delivery handles. hen the proper coin or key X isintroduced in the slots 48, 48, segments 49, 49 which are fixedlymounted upon the shaft 39 at either end of the feed box A, may berotated. As above explained, the rotation of the shaft 39 rotates thequadrants 40, 40 to raise the section 36. The extent to which thesegments 49, 49 are rotated is regulated by rack bars 50, 50. Theposition of the rack bars 50, 50 with reference to the segments 49, 49and the gear teeth 51, 51 thereof, is adjusted by set nuts 52, 52 whichthreadably engage elongated screws 53, 53. The elongated screws 53, 53are rigidly mounted upon arms 54, 54 at the upper ends whereof aremounted handles 55, 55. Vith a mechanism constructed as thus describedthe handles 55, 55 are drawn toward the slots 48, 48, causing the rackbars 50, 50 to engage the heads 56, 56 of the segments 49, 49 to movethe teeth 51, 51 into position to engage the teeth of the rack bars 50,50 and to thereby rotate the shaft 39. By adjusting the nuts 52, 52 toadvance or retract the rack bars 50, 50 upon the screws 53, 53, it willbe seen that the extent of movement imparted to the segments 49, 49 andthe shaft 39 may be regulated. Thus, beginning at the slot 48 marked bythe numeral 1, the rack bar 50 is adjusted so thatat the extreme throwof the handle 55 the rack bar 50 strikes upon the head 56 and does notmove the same. The rack bar 50 connected with the handle 55 operating inline with the slot designated by the numeral 2 is then adjusted to rockthe segment 49 to cause the section 36 to lift to deliver into thehopper 38 an added quantity of grain, doubling the quantity delivered bythe first operation. Again the rack bar 50 attached to the handle 55 inline with the slot 48 designated by the numeral 3 is advanced to rotatethe segment 49 to rock the shaft 39 to raise the section 36, so thatthere is delivered into the hopper 38 suflicient grain to increase thequantity to three times the original delivery, or that delivered byoperating the handle 55 opposite the numeral 1. The increasingadjustment of the rack bar 50 is carried forward for those rack barsattached to the handles 55 set Opposite the slots 48 bearing thenumerals 4, 5 and 6.

When a new lot of grain is purchased a measured test quantity is runinto the hop per 38 and verified for weight. If the grain be found to beheavier or lighter than the standard, the nuts 52, 52 are adjusted sothat the rack bars 50, 50 are advanced or retracted, as the case may be,to rock the shaft 39 to a greater or lesser extent. In this manner itwill be seen that the quantity of grain delivered by the machine isregulated according to the weight of the grain, while the operation ofmeasuring is performed as in handling liquid materials.

The rack bars 50, 50 are provided with side slots 57, 57, the upperextensions of which are formed by graduated plates 58, 58. The plates 58are secured by means of screws 59, 59 to the rack bars 50. The slidingblocks 60 are provided with slotted pads 61, in which are rigidlysecured the arms 54, 54. The blocks 60 have in the forward ends raisedsides 62, 62, on which are secured coin or key holding blocks 63, 63.These blocks 63 are provided with slots 64, 65 and 66. The slot 64 isprovided to admitfrom the forward end of the block 63 an arm 67 set outfrom the side of a crank arm 68, which is mounted upon a shaft 69. Theslot 65 is provided to admit from the rear end of the block 63 the endsof levers 70, 70 when the block 63 is retracted. The slot 66 is providedto aline with the slots 48, 48 in the plates mounted upon the top of thefeed box A to receive the various coins or keys X. By means of thegraduated plates 58, all of the racks 50 may be advanced to the samedegree, each ofthe blocks 60 being provided with an index 58 to aid inthis adjustment. Further, by means of the graduated scale, the handles55, 55 may be advanced to carry the blocks 60 forward to measurefractional parts of the unit for which the blocks 60 are designed.

The operation of the handles 55, 55 and the consequent rocking of theshaft 39 raises and lowers the section 36. Until the grain is permittedto flow into the pipe 29 this operation is futile. The grain is notpermitted to flow into the pipe 29 until the plate is drawn to theposition wherein the opening 35 is presented under the pipe 27. Theplate is pivotally connected at 71. to a lever 72 which is pivoted at 73on the top 26 of the feed box A. The plate 34 is locked in the positionillustrated in Fig. 1, where the opening 35 is out of alinement with thepipe 27, by means of a latch head 752 which extends into a recess 75formed in the side of the plate 34. The latch head 74 is seated in arecess 76 formed in the under side of the top 26 of the feed box A. Thelatch head 74; is carried on the end of a latch arm 77, which is rigidlysecured by a set screw 78 upon the shaft 69. The latch arm 77 isprovided with a heavy counterweight 79 whereby the arm 7 7 is maintainedin a horizontal position to raise the head 74 into engagement with therecesses 75 and 76. While the head 7 4 remains in the recess 75, theplate may not be moved by the lever 72. It is only when the coin or keyX, as shown in Fig.4 of the drawings, is carried by the block 63, thatthe shaft 69 is rocked so that the head 74 is depressed out ofengagement with the recesses 75 and 76. The operator may then grasp ahandle 80 and throw the lever 72 about its pivot 73 until the opening 35is brought beneath the pipe 27. In this action the pivot is permitted toslide in a slot 81 formed in the lever 72. The plate 34 is guided in itsaction by the guide rails 82, 82 and a slot 83 formed in a guide plate 81, rigidly mounted upon the top 26 of the feed box A. When the openingis alined with the pipes 27 and 29, as just above described, the trapdoor 37 is raised to the closed position illustrated in Fig. 7 of thedrawings, and the grain delivered by thus opening the pipe 27 is held inthe hopper 38. The quantity of grain delivered is regulated by theselection of the handle 55 and instrumentalities connected therewithwhich have been operated with the coin or key X contained in the block63, which coin or key X has rocked the shaft 69 to permit the movementof the plate 3 1. The door 37 is hingedly mounted at 85 on the underside of the hopper 38, and is operated from a shaft 86 to which it isconnected by means of a crank arm 87 and a connecting link 88 pivotallyconnecting the arm 87 and the door 37. The shaft 86 is rocked bydepended arms 89, 89, which are rigidly secured at 90, 90 to the slidingblocks 60. The arms 89 are advanced to impinge upon upright arms 91, 91upset from a block 92 rigidly attached by means of set screws 93 on theshaft-86. Each of the blocks 60 is provided with one of the arms 89,consequently, with the operation of each of the handles-55 the door 37is closed. Each of the arms 54: is provided with a pivoted latch 94, 94,which drops into a slot formed in the top 26 of the feed box A, andlocated at the extreme forward and rearward positions of the arms 5%.When the latch 9% drops into the advanced slot 95, the arm 54:, andparts c011- nected therewith, are held in their advanced position. Thisholds the door 37 closed. The door 37 is maintained in the closedposition after the handle 55 is released and the block 60 is retractedto near its normal position. The shaft 86 is prevented from rocking tothe open position for the door 37 by arms 96, 96, the ends of which arecrooked to strike within recesses 97, 97 of rack arms 98, 98. Vhen,however, the blocks 60, and with them the arms 89, are retracted totheir normal position, the vertical extensions 99, 99 thereof strikeupon heads 100, 100 of the rack arms 98, 98, raising the same until thearms 96 are freed, allowing the shaft 86 to rock and open the door 37The action of the arms 89 is guided by guide arms 101, 101 which areextended through slots 10:2, 102 in the arms 89. The guide arms 101 areprovided with recesses 103, 103 to receive the heads 100 of the rackarms 98. The rack arms 98 are pivoted upon a shaft 104 extendedlengthwise of the feed box A. hen the block 63 is holding the coin orkey X, and is advanced to this forward position, the coin or key Xstrikes upon the arm 67, as above described, and rocks the shaft 69 sothat the plate 3 1 may be moved. At the same time it depresses a hook105 to fall over a pin 106 set out from the block 63. This engagementbetween the hook 105 and the pin 106 prevents the retraction of theblock 63 and parts connected therewith, while the arm 67 is engaged bythe coin or key X, and while the shaft 69 is rocked to depress the lever77. The shaft 69 cannot be rotated to free the hook 105 from the pin 106until the recess 75 in the plate 34: is returned to its normal position,so that the head 74 may be raised upward through the said recess andinto the recess 76. It therefore becomes necessary to close the plate 31over the pipe 27 before the door 37 may be opened by the retraction ofthe block 60 and the arm 89 connected therewith.

The coin or key X is extracted from the slot 66 by means of the levers70, 70. These levers are pivoted at 107, 107 upon structural plates 108,108 of the machine, and are provided with beveled ta'il pieces 109, 109,so adjusted as to be wiped by pins 110, 110 mounted in extensions 111,111 formed on the blocks 60. Vith the advance of each of the blocks 60,the pins 110 wipe the beveled ends of the levers to throw the sameoutward to extend the forward ends of the said levers inward and intothe path of the coin or key X, when held in the said slot 66. At theforward end of the block 63, extended across the slot 66, is a pivotedapron 112. This serves to maintain the coin or key X in the block 63during the operation of the machine. WVhen, however, on the return ofthe block 63, the lever 70 striking behind the coin or key X, the apron112 yields to the pressure from behind, permitting the coin or key X topass out of the slot 66 and the block 63. When in the course ofoperation a second coin or key is Placed in the slot- 66 and advanced tothe forward posi tion, the coin or key X strikes upon the back of theforward end of the lever 70,

moving it to one side to pass the coin or key X, and to reset the tailpiece 109 into the path of the pin 110. It will be understood that inthe operation of the blocks 60, that the coin or key X is extracted fromthe pocket holding the same prior to the opening of the door 37. In thismanner is prevented the double use of the said coin or key. When thecoin or key X is thus ex tracted from the block 63, it is precipitatedprevented the double use of the said coin or key X to boxes 11 1, 114;which are provided each for a certain class or character of the saidcoins or keys X.

The various parts of the said machine are hinged at 115, 115, whichhinged parts are suitably locked by pad locks 116, 116. By means of thisarrangement the working parts may be readily accessible to the partycarrying the key, while being secured against tampering by outsideinterference.

The extent of rotation of the shaft 86 is governed by an extension 117and a block 118. The extension 117 may be given sufficient weight tocause the action of the shaft 86 and door 37 to operate more quickly.The rack arms 98 are guided in their movement by guide plates 119, 119set out from the side of the feed box A.

Having an apparatus of the character described, and as shown in thedrawings, the operation is as follows :It will be understood that thevarious handles 55, and operating mechanism connected therewith, areconnected by means of coins or keys of different sizes or shapes, whichare designed to be inserted in the various slots 48 prior to moving thevarious handles 55. As a part of the system in which this apparatus isemployed the various hostlers or drivers are supplied with one or morecoins or keys applicable to the known needs of his team. For instance,it is designed that a horse being driven by a certain driver shouldreceive two pounds or two quarts of grain, therefore that driver wouldbe supplied with a coin or key which would fit within the slot l8bearing the designating numeral 2. When now the driver desires to obtainthe grain, he first places the coin or key within the slot 48 adapted toreceive the same. The coin or key drops into the slot 66 of the block 63where it is held. The handle 55 opposite the said slot is then advanceduntil the latch 94 rests within the slot 95. The coin or key X impingesupon the arm 67 and rocks the shaft 69 so that the hook 105 is depressedover the pin 106, and the latch arm 77 is depressed to withdraw the head74 from the recesses and 76. This rocking of the shaft 69 looks theblock 63 and parts connected therewith in operative position, whilereleasing the plate 34. \Vith the handle 55 in this position the drivernext grasps the handle of the lever 72- and draws the same to one sideuntil the opening 35 in the plate 34 is advanced under the pipe 27.

In advancing the handle 55, as above described, there has also beenadvanced the arm 89 connected therewith, which has impinged upon the arm91, causing the shaft 86 to rock, and through the connecting lever 87and the link 88 to close the door 37. It is while the door 37 is in itsclosed position that the plate 34 is moved to present the opening to thepipe 27, and the grain delivered from the hopper 22 is permitted to flowinto the hopper 38 until the grain in the hopper reaches the heighttherein at which the grain ceases to flow under the edge of the section36. Simultaneously with the closing of the door 37 and the advancing ofthe block 63 bearing the coin or key X, there has been advanced the rackbar 50 connected with the handle 55 opposite the slot in which the coinor key X was deposited. As above stated, the bar 50 has been adjusted sothat in the forward movement of the handle 55 the said bar engages thesegment 49 set in its path to rotate the shaft 39. The extent of therotation of the shaft 39 raises the section 36 on the pipe 29proportionately. in the present illustration, by operating the handleset opposite the slot designated by the numeral 2, the engagementbetween the rack bar 50 and the segment 49 will cause th shaft 39 torotate sufficiently to raise the section 36 to permit suflicient grainto flow under the edge of the said section, to add to the quantitycontained within the pipe 29 and section 36 below the plate 34 when thesame is closed, to equal the two pounds or quarts, as the case may be,designed to be delivered by the operation of the said handle 55. It willbe noticed now that the door 37 is closed, and cannot be opened untilthe handle 55, which has been advanced, is re tracted. It will be seenthat the handle 55 may not be retracted until the hook 105 is registerthe recess (5 with the head 74 requires that the plate 34 shall be movedinto a position wherein the pipe 29 is closed. The operator here movesthe handle 80 to its normal position. He then draws backward to itsnormal position the handle 55. Into the receptacle which he has placedbelow the door 37 is emptied the contents of the hopper 38 by theopening of the door 37. The door 37 is thus opened by the extension 99of the arm 89 striking upon the head 100 of the rack arm 98, releasingthereby the arm96 from engagement with th said rack arm, andperi'nitting thereby the weight of the door 37 and the arm 96 to throwthe door 37 to its opened or delivering position, It will be found thatthe quantity of grain thus delivered equals two units of the weight ofthe purchased grain.

Where a system is employed embodying the operation of an apparatus suchas described, it will be found that the tally of the distribution countsfor the total bulk purchase of grain. As an aid to this tally will bethe various coins or keys X.

As the handles 55 are retracted to their normal position, the coins orkeys X are extracted from the block 63 and delivered into the variouschutes 113, to be guided to the individual boxes or receptacles 114.Each of these receptacles represents, at the end of a day, week or otherperiod, the number of operations of the handles 55 set opposite the slotto which each of the various boxes 114 are connected. Hence, by countingthe number of coins or keys X in any one box, and multiplying the numberby th numeral designating the slot feeding the said box, there isarrived at the resultant number of units of grain delivered through themanipulation of th particular handle set opposite the particular slotconnected with the box in question. Hence, if there should be found tobe one hundred coins or keys X in the box feeding through the slotnumbered 6, this would show that six hundred pounds, or quarts, as theunit might be, had been delivered through the machine by the operationof the handle 55 set opposite the numeral 6. By totaling the resultsregistered in each box will give the grand total of the number of unitsdelivered through th machine in a given time.
